Specification of Letters Patent. Patented June 27, 1922.

Application filed .Tune 15, 1921. Serial No. 477,671.

To all whom it may concern.

Be it known'that I, FRED. T. FonHL, a citizen of the United States, andresident of the city of New York, borough of Brooklyn, county of Kings,and State of New York, have invented a new and Improved Pliers, of whichthe following is a full, clear, and exact description.

My invention aims to provide certain new and useful improvements inpliers, and more particularly such pliers as are intended for use byopticians and oculists.-

It is a well appreciated fact that any number of pliers have beenconstructed which were to be utilized in associating a clamping platewith the rims of an eyeglass. For the most part these pliers haveoffered objections in that primarily they were cumbersome inconstruction, and relatively expensive in manufacture, and furthermorethe rims have become crushed if the pliers were not handled with extremecare.

Aside from the difficulties mentioned pliers of this nature haveheretofore marred the exterior of the clamping plates while bending thelatter so that the bright surface of these plates has been scratched andrendered unsightly, it being also noted in this connection that it iscustomary to utilize different sizes of pliers corresponding to the sizeof the rim with which they were to cooperate.

With these defects in mind, my present invention aims to provide a plierwhich shall. be extremely simple in construction and capable of beingmanufactured at a nominal figure, and by means of which the Optician oroculist may readily associate the plate of an eye-glass with the rim,without any danger of the latter becoming crushed incident to carelesshandling of the pliers.

A further object of my invention is the construction of a device of thecharacter stated which will not mar the surface of the clamping plateand which shall be constructed in such a manner as to be capable ofbeing utilized in connection with widely varying sizes of eye-glass rim.

Still further objects of my invention will appear in the annexedspecification taken in connection with the drawings which latterillustrate one practical embodiment of the same, and in which;

Figure 1 is a perspective view showing my pliers in use.

Figure 2 is a side View thereof.

Figure 3 is a front view of the same, and

Figure & illustrates one of the jaws.

Referring now more particularly to F igure 1 it will be seen that thepliers include in the usual manner, a pair of farms 5 pivotally securedas at 6 and presentin a pair of jaws 7 which will be moved toget er uponthe arms 5 comprising the handles being moved towards each other as inthe usual type of pliers.

Attention is invited to Figure 2, and it will be seen in this figurethat both of the jaws are curved in the same direction for a purposehereinafter specified, and reference being had to Figure 4, it will benoted that each of the jaws presents a groove 8 extending transverselyacross the inner face of the same, a further groove 9 being alsoprovided, which groove has one of its ends in communication with thegroove 8 at a point subsequently intermediate the extremities thereof,the opposite ends of this latter groove extending to the outer end ofeach of the jaws.

Further it will be seen that a set screw 10 is associated with one ofthe jaws, and hasits inner end contacting with the inner face of thesecond of the same. Thus the jaws may be prevented from contacting withEach other, for a purpose hereinafter speci- It will be seen that byvirtue of the curvature of the jaws 7 that the same may be introducedwithin the frame of the eye-glass, as has been shown in Figure 1, andthe outer ends of these jaws presenting the grooves 8 and 9 will lie ina plane forming a continuation of the plate 11 to be bent, and it willbe appreciated that by this construction any part of the frame 12 willbe equally capable of being operated upon by this type of plier, itbeing also noted in this connection that the groove 9 will bridge thenose-piece or any other element extending from the plate to be clamped.

Furthermore the arcuate interior of the groove 8 conforms to thecurvature of the frame 12,. and it will be understood that the plate 11will be properly applied to the frame and not in the slightest distortedthus avoiding any marring of the face of the same, it being also notedthat the set screw 10 may be adjusted to limit the movement of the jaws7 towards each other, thus preventing any crushing of the frame 12 tothe-diameter of which it is adjusted.

Thus it will be seen that all of the objects set forth in the preambleof this specification have been accomplished, and it will be understoodthat numerous modifications of 5 structure might readily be resorted towithout in the least departing from the spirit ofmy invention, which Iclaim as;

A plier including a pair of jaws having their inner faces similarlycurved throughout their entire length and extending normally parallel toeach other, each of said jaws being formed with grooves adjacent itsouter end.

FRED. T. FOEHL.
